+# System-2.1: DUT Reboot Test
+
+## Summary
+
+- Configure BGP, IS-IS and redistribution
+- Validate control-plane and data-plane post reboot
+- Validate P4RT, gNMI, SHH connectivity post reboot
+
+## Testbed type
+
+*   https://github.com/openconfig/featureprofiles/blob/main/topologies/atedut_2.testbed
+
+## Procedure
+
+#### Initial Setup:
+
+*   Connect DUT port-1, 2 to ATE port-1, 2
+*   Configure IPv4/IPv6 addresses on the ports
+*   Configure IPv4 and IPv6 IS-IS L2 adjacency between ATE port-1 and DUT port-1
+*   Configure IPv4 and IPv6 eBGP between DUT Port-2 and ATE Port-2
+*   Advertise a few IPv4/v6 BGP routes from ATE to DUT through the BGP session
+*   Configure redistribution of the BGP prefixes to IS-IS on the DUT
+
+### System-2.1.1
+#### Pre Reboot Validation
+---
+
+##### Validate SSH connectivity
+*   Verify SSH connectivity to the device works
+
+##### Validate P4RT connectivity
+*   Configure P4RT id and node-id (device_id) with port-1 interface
+    *  Linecard `device_id = 111`
+*   Using P4RT Read RPC send a ReadRequest for port-1 counters
+*   Ensure a ReadResponse is received
+
+##### Validate Traffic Forwarding
+*   Initiate traffic from ATE port-1 to the DUT and destined towards the BGP redistributed routes
+*   Validate that the traffic is received on ATE port-2

+### System-2.1.2
+#### Post Reboot Validation
+---
+##### Reboot the DUT
+*   Reboot the DUT and wait for it to come back up
+
+##### Validate SSH connectivity
+*   Verify SSH connectivity to the device works
+
+##### Validate P4RT connectivity
+*   Configure P4RT id and node-id (device_id) with port-1 interface
+    *  Linecard `device_id = 111`
+*   Using P4RT Read RPC send a ReadRequest for port-1 counters
+*   Ensure a ReadResponse is received
+
+##### Validate Traffic Forwarding
+*   Initiate traffic from ATE port-1 to the DUT and destined towards the BGP redistributed routes
+*   Validate that the traffic is received on ATE port-2
